City will play Watford in the next round of the FA Cup following their replay win over Blackburn. In truth, the away side never really looked like upsetting the apple cart, but they did make life difficult for the hosts. Dzeko struggled to find the target – first, with a header inside the area, second, he skied a blast from a touch down by Fernandinho on the edge of the box, and third, he blasted a long, long, long range effort over.

In between his chances, Marshall curled a free kick straight into Pantilimon’s arms after Cairney was felled by Nastasic on the edge of the box. Garcia blasted a shot from range that looked to be curling into the bottom corner, until Robinson beat it away low to his left.

Ten minutes before half time, City got even closer. Navas beat Marshall on the right flank and fired in a low, driven cross through the six-yard box. First Negredo, then Fernandinho threw themselves at it, but they were both inches away from touching it into the net.

As it looked like the hosts were going to be frustrated at the break, the Blues found the breakthrough: Fernandinho’s cross was missed by Dzeko, but behind him was his strike partner in Negredo – the Spaniard met it and nodded it into the corner of Robinson’s net, with virtually the last touch of the half.

And, the same man scored with virtually his first touch of the second half. Kolarov picked up the ball on the left flank and crossed from deep towards the run of Negredo. The covering defender couldn’t intercept and the striker dinked it over the top of the substitute goalkeeper Eastwood.

Blackburn responded with some good chances. King found space in between Lescott and Nastasic to flick a header towards the top corner, but he got too much on it and headed over. A few moments later, the same man escaped the attention of Nastasic to go one-on-one with Pantilimon, but the Romanian keeper stood up well to make the save.

With just over 20 minutes to play, though, the hosts effectively ended the game. Navas raced through on the right to a Milner pass and, after wriggling his way to the by-line, he played it in low for Dzeko at the front post. The Bosnian’s effort towards the top of the net was too powerful for Eastwood.

Blackburn were deflated and, when Pellegrini introduced Aguero into the action, the Chilean was rewarded as the Argentine scored with his second touch. Dzeko received the ball inside the box on the left and he squared for his strike partner. Aguero took a touch to control and spin, then his second – a low shot – beat both covering defenders and the goalkeeper.

Goal number 99 for the season came with ten minutes to play. In a move not too dissimilar to create the third, the Blues added their fifth of the evening with the same combination – Navas to Dzeko. The Bosnian got across his man to touch the Spaniard’s cross around the corner and into the net at the near post.
